Here our focus is on developing the side delt
Head. This movement really defines your shoulders.

Implementation:
(A) Stand straight, with your arm
at your side, grasping the handle attached to the floor-level pulley.
(B) Having
your Arm straight, lift the weight up in an arc in one smooth controlled manner
until It is higher than your head. Lower your arm slowly and resisting all
the way till your
Arm is back at the side of your thigh. Finish your reps, then do the same
set to your Other arm.
